This application note was developed by Morningstar Corporation and is based on
information from Aquion Energy. The information is intended as a guide to help
configure settings on various Morningstar controllers to charge Aquion
batteries. Performance may vary depending on use conditions and application.

Aquion Batteries

Non-toxic. Non-Flammable.

Long Lasting – 3,000 cycles at 100% discharge

Low maintenance

8 year warranty

Partial State of Charge and very low State of Charge Tolerant

Slower rates of charge and discharge Does not need a Battery Management
System

Custom settings are recommended for best results. However, there are
factory PreSets that can be enabled with alternative DIP Switch settings
which may be applicable for a particular model, system and environmental
conditions.

Different controllers will have different options and charging
parameters. Please use the information below and make adjustments as needed.
Not all settings critical and certain conditions may or may require some of
the optional settings. Review all of the settings and consider what
adjustments may be required for your particular system.

Max. Charge Limits can be imposed for the TriStar MPPT and ProStar MPPT
controllers. The downloadable MSView Setup Wizard files for the TriStar MPPT
and ProStar MPPT controllers have Enabled Battery Current Limits for a single
battery stack. These settings can quickly be edited in MSView for multiple
stacks if there are multiple stacks or modules.

All custom settings must be programmed with 12V nominal voltages which
will be multiplied accordingly for 24V and 48V battery banks. DIP Switch
nominal voltage multiplier settings are recommended.

Charging can be reduced and disabled during low temperatures with the
ProStar and ProStar MPPT controllers. The Morningstar Relay Driver can be
used to disable both charging and loads during cold temperatures.

* – Settings must be programmed with 12V nominal voltages with all
Morningstar controllers and will be multiplied by 2 or 4 for 24V and 48V
batteries respectively. Use DIP Switches to set the battery voltages as
indicated in the DIP Switch tables above.

** – Float Timeout is the cumulative time that voltage drops below the
Float Target Voltage before returning to Bulk/Absorption. If a system drops
out of float this setting will attempt to recharge the battery late in the
day

*** – High Voltage Disconnect/ Reconnect will disable charging when there
is overcharging from other sources.
